Too much assymetric IPD may cause some degree of eyestrain in any VR hmd on the market unless a new model allows physical per eye IPD adjustment.
However, most of us know this is not the case with Pimax. So many people with almost perfect sysmtrical IPD also report eyestrain issues…
Why I said %100, is a fact from my experience as an owner of various VR hmds like Rift, PSVR, Lenovo, Go, Samsung Gear VR. No matter what I do with my Pimax 5k+ even with latest beta drivers as someone with symetric IPD, eyestrain does not go away and this is not about horizontal or vertical alignment of wearing this hmd, bacause I have tons of different facepads, and did already my best to accommodate Pimax for my headshape. After all I spent my last 5 years dealing with all those various VR hmds mentioned and more than 20 different google cardboard hmds that I still keep as souvenir.
Rather that correcting this issue at later iteration (that is another MUST of course as you accepted), as someone who supported Pimax in 2017, I would like this company to offer a honest, decent, scientific solution for all of us who helped them, trusted them, and supported them with millions of $$$.
There must be a better way out of this thing rather than putting the blame on consumers and pledgers side as they are not ignorant at all when it comes to VR.
